The cluster is small in absolute dollar terms ($11.9M total) and dominated by one fund (Assenagon). Monitor next 13F filing for whether these positions were maintained or reversed, and watch for insider buying or earnings catalysts that could corroborate the thesis.
Executive Summary
Three institutional asset managers increased their ZG positions in Q3 2026, led by Assenagon Asset Management which more than doubled its stake. Total net buying was $9.9M, but the dollar amounts are small relative to Zillow's market cap, and the 45-day reporting lag means positions may already be unwound.
